SOUND-PRODUCING APPARATUS.

To all whom it may concernk Be it known that I, CHRISTIAN S. Gna- LACH, a citizen of the United States, residingat Brandon, in the county of Fond du Lac and State of Wisconsin, have invented new and useful Improvement-s inv Sound- Producing Apparatus,;of which the following is a specification.

This invention relates to a sound producin apparatus and has for its primary object to generate a plurality of sound waves of different characteristics .such as would be I necessary in the moving picture art.

An object of the invention'is to provide suitable mechanism by means of which sound waves of different characteristics may be taken from a sound record.

- Another objectof ,the invention is the ,novel manner of moving singularly orcol- 'lectively a plurality of stylus arms into engagement with sound lines of a record.

Besides the above my invention is distinguished in the novel manner of associating the'partsso that the apparatus may be used as an ordinary talking machine or to create sound waves under manual control.

With these and other objects in view the invention will be better understood from the following detailed description taken in con- .nection with the accompanying drawings, wherein, V

Figure l is a front elevation of the apparatus. A

Fig. 2 isa top plan view thereof. Fig. 3 is a side elevation. Fig. -4. is a verticalsectional view. Fig. 5 is a horizontal sectional view on the line 55 of Fig. 4.

Fig. 6 is a sectional view on the line 66 of Fig. 4. Fig. .7 is a transverse sectional view of the cabinet on-plane of line 7-7 of Fig. 4.

Fig. 8 is an enlarged view of the operating mechanism for one of the stylus arms.

Fig. 9 is a detail viewof a part to be hereinafter described. 'Fig. 10 is a vertical sectional View of the cabinet showing the parts associated with a plain ordinary record,-an d Fig. 11 is a plan view of the improved form of sound'records.

Referring to the drawingsthe numeral 1' designates the casing of the apparatus supporting within, the ordinary turn table 2 and motor 3 of a talking'machine. The horn 4 of the talkingmachine is held sta- Specification of Letters Patent.

' tionary and has a sliding connection with the -tone arm 6 having spaced branches 7 and 8. To the free end of each branch issecured a reproducer 9. The centers of the rep'roducers are arranged in alineinent with each.

other and connected to the ends of the flex ible elementlO. Slidably mounted. directly H above the turn table-2 is a frame 11 includ' uprights 12 supportedby the casing 1.

Supported by the frame is a'plurality of pivoted levers 14 one for each sound of a certain characteristic that is to be produced.

The pivot of the lever 14 is arranged adjacent one end while the opposite end moves in a guide 15 and continuously. bears upon one arm 16' of a. centrally pivoted lever 17, the other arm 18 of which being acted upon by a rod 19 that in turn is actuated by a member 20 in the form'of and having the action of an ordinary piano key. From this. latter arrangement it will be seen that each time a member 20 is depressed, the lever 14 will be free to move about its pivot. stylus arm 21 has a central portion pivoted to an intermediate portion of the lever 14 by a pin 22. One end'of the stylus arm is formed into an eye 23 having a connection with one end of a flexible element 24, the

other end of which is connected to the flexible element 10 at a point in the length of the latter. As far as I have proceeded it will be seen that when the member-20 is depressed, movement will be given to the lex e'r 14 for bodily moving the stylus arm toward and away" from the sound lines of thereco'rd' upon the turn table. As the stylus arm vibrates due to the sound lines of the record, the element 10 will be set into vibration through the action of the element 24 with the result that both of the vibratory members of the reproducers 9 aregiven a vibratory motion identical to that of the stylus arm. v

I have found out in practice when using my apparatus that it is advisable to construct a special record as illustrated in Fig. 11 of the drawings. This record has a number of concentrically arranged sound lines 25 each of a different sound characteristic,

that is to say, the first line may produce the sound of a drum, the second that of a horse trotting and the others varying accordingly depending entirely upon the result sought.

In the drawings I have illustrated my invention so constructed as to be capable of .Qbeing converted into an ordinary talking machine for'playing ordinary records. To

accomplish this the frame 11 is elevated high enoughto' placethe tone arm 6 a predetermined distance above the horn 4, after Which thejtone'arm' 26 is substituted. Rotatably mounted in the tone arm 26 at'difierent times is a reproducing device 27 acom- 1 posed of a reproducer 29 constructedto ac commodate lateral sound waves ofia; record and a-reprodu'cer 30 to accommodatevertr' cal sound Waves.

To take care of expansion and contraction of the element 10, I provide the turn buckle 30 that mayhave a: rigid connection With the branches of the tone armor may be connected directly to the frame of the rep'ro ducers.-

It is'to be understood that While all of the several features of my improved apparatus havespecial cooperation With one another and together constitute a particularly eflective mechanism for the purpose in vieyv, certain of these features may be applied in other relations and 'll therefore desire tocover the comblnatlon present in the sev-.

' limited in these articulars or in an others P a Y except as set forth in the appended claims. What I claim is '15 A sound producing apparatus comprising in combination with a talking machine having a fiat turn table, a tensi oned element connected to the vibratory member of the reproducer of the talking machine, 'a record formed With a number of concentric sound lines, means normally out of engagement With and mounted to move into engagement With the sound lines for transmitting Vibratory motion from the record to said element, and means for elevating; the first mentioned means a considerable distance abovethe turn table. :1

2. A sound producingapparatus com risr ing in combination With a talking mac ine,

a tensioned element connected to the vibratory member of the reproducer of the talking machine, a record. formed With a plurality of concentrically arranged sound lines, a plurality of stylus arms equal in number to and adapted to engage the sound lines, aframe on which said stylus arms aremounted, means for holding the stylus arms from engagement With the sound lines, and means for elevating said frame a considerable distance above the table.

3. A sound producing apparatus comprising in combination With-a talking machine having tWo spaced reproducers, a flexible element connecting the vibratory members ofthereproducers together, means for varying the tension of said elen1ent,-and a plurality of devices each capable of transmitting'vibratory motion from a record to said element.

I 1 5. A sound producing apparatus comprisso a ing incombination with the turn table of a talking machine a frame mounted for sliding movement above said turn table, a

6. A sound producingapparatus comprising in combination-With the turn table of a' talking machine, a frame mounted for sliding movement above said turn table, a

In testimony whereof ll affix my signature.
